CABLE srnnronna AND HO DER.

Specification of Letters Patent.

Patented ll'lar,23,1920.

To all whom zit may concern:

isle it known that I, GEORGE J. HILDAI-IL, a citizen of the United States, residing at Clarklield, in the county of Yellow Medicine and State of Minnesota, have invented certain. new and useful Improvements in Cable Stretchers and Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same.

My invention relates to cable stretchers and holders intended for general list-abut especially adapted :tor use in the repairing of check row wires for planters. As is well known, check row wires for planters extend across a field and are anchored at their two ends. It is now necessary, when one of these check row wires breaks, for the ope 'ator of a planter to go to one end of the field, loosen the end of the check row wire, return to the break therein, make the necessary repairs, again return to the end of the field, anchor the loose end of the check row wire and then return to his planter. This, of course, takes considerable walking on the part of the operator and often necessitates a considerable delay. By the use of my invention, an operator may draw the broken ends of a check row wire together and connect the same with an emergency link without releasing either anchored end of the check row wire.

To the above end, gene ally stated, the in vention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings Figure 1 shows the invention as used to connect the ends of a broken anchor check row wire to permit the application of an emergency link;

Fig. 2 is a view of the two sections of the check rowwire after the ends thereof at the break have been connected by an emergency link;

Fig. 3 is a bottom plan view of the invention; and

Fig. 4: is a view partly in side elevation and partly in section taken on the line 4 l of Fig. 3.

The numeral 5 indicates the two sections of a broken check row wire of the coimnonly used type comprising, a multiplicity .ol straight links loosely connected by interlocking eyes which afford knots or irbutments to trip the seed-dropping mechanism of the planter, as is well understood. As shown in Fig. 1, the outer ends Lot the check row wire 5 are attached to anchors-takes 3 and the sections oi. the broken link otfthe wire havebeen removed.

The improved cable stretcln-n" and holder includes a casing 7 preferably ctorlned fmm asinglc piece of sheet metal bent to form a pair of laterally spaced sides 8 comrectrd at their edges by a peripheral web 9 having a gap to afford a passageway 10. The web 9, at one end of the opening 10, which may be termed the upper end for thesake of convenience, is rolled around a pin 11, to afford a cable guide 12. In some instances, it might be desirable to journal an antifriction roller on the pin 11. Formed in the web 9, at the lower end of the passageway 10, is a V- shaped cable-holding notch 13. A groove sheave 1-1 is mounted in the casing 7 and loosely journaled on a pin 15, secured in the sides 8 of the casin A cable carrier 16, in the form of a sleevelike body, is provided at its inner end with a pair of laterally spaced prongs 17 which embrace the casing 7 and are pivoted on the projecting ends of the pin and connect said cable carrier thereto for circumferential swinging movement in front of the casing opening 10. The longitudinal axis of this cable carrier 16 extends substantially tangentially to the bottom of the groove in the sheave 14;. Anchored in the web 9, at a point diametrically opposite the center of the passageway 10, is a radially projecting stem 18 having at its free end a hook 19 arranged to interlock with one of the links of the check row wire 5 and engage one of the knots therein to secure the cable stretcher and holder to one of the sections of the broken check row wire 5.

A pulling cable 20, as shown in the form of a rope, has secured in one of its ends a hook 21 arranged to interlock with one of the links of the other section of the check row wire and engage one of the knots to anchor the cable thereto. The other end of the cable 20 is extended through the pas sageway 10 over the sheave 14 and its loose end is extended outward through the passageway and sleeve-like body of the cable carrier 16.

, a By attaching the cable 20 to one section of the check row wire 5 by means of'the hook 21 and the casing 7 to the other section thereof by the hook 19, the broken ends of the check row wire may be drawn sufficiently near together, by pulling on the loose end of the cable 20, for the application of an emergency link 22 thereto. After the broken ends of a check, row wire 5 have been drawn together sufliciently near, for the application of the emergency link 22, saidencls are held thereto by taking hold of the cable carrier 16 and swinging the same away from the main body of the cable 20 to kink said cable-into the lock notch 13. The pull on the cable 20 will, of course, securely hold the cable in the lock notch 13. To release the cable/5 from the lock notch 13, it is only necessary to pull on the free end of the cable 20 and at the same time swing the cable carrier 16 toward the main body of said cable to take the kink out of the cable and carry the same out ofsaid lock notch.

In attaching the cable stretcher and holder to the sections of the check row wire,

the hooks 19 and 21 are preferably applied to the second links from the broken link, thus leaving the first links free for the application of the emergency link 22 thereto. The emergency link 22 is preferably secured to the adjacent links of the check row wire by transversely divided links 23, as shown in Fig. 2.

What I claim is 1. A cable stretcher and holder comprising a casing having formed therein a cable holder, a sheave journaled in the casing, a cable arranged to run over the sheave, and a cable carrier on the casing for moving the cable into and out of engagement with the cable holder.

I 2. A cable stretcher and holder comprising a casing having formed in its peripheral web a V-shaped cable-holding notch, a sheave journaled in said casing, a cable arranged to run over the sheave, and a cable carrier on the casing for moving the cable into and out of engagement with said IIOtrll.

In testimony whereof I ailix my signature in presence of two witnesses.
